The background was created with a fog machine. During shooting, we filled the space with as much fog as we could, and then we let it drift down and settle a bit. There was one shop light sitting on a ladder behind the subject. I put violet color film in front of the light. Later I changed the color to orange in PP. You can see remnants of the violet color on the outer edges. I'm not an avid Lou Reed fan, so I was not sure how this would do.
